System for preparing high-quality gasoline through component oil refining hydrocarbon recombination hydrogenation and method thereof

摘要

The invention discloses a system for preparing high-quality gasoline through component oil refining hydrocarbon recombination hydrogenation and a method thereof, which is characterized by comprising an extraction system, a distillation system and a hydrogenation device, wherein the upper part of the extraction system is connected with the distillation system through a pipeline, and the lower part of the extraction system is connected with an extract oil hydrogenation device through the pipeline; light gasoline is recovered by the upper part of the distillation system through the pipeline; the lower part of the distillation system is connected with the heavy gasoline hydrogenation device through the pipeline; and reformate or ethylene feed are recovered through the lower part of the heavy gasoline hydrogenation device through the pipeline. The system for preparing high-quality gasoline through component oil refining hydrocarbon recombination hydrogenation and the method thereof has small scale and low cost and can remove olefin, mercaptan sulphur and diene.
